It seems to me that having a bowl of fruit in a hospital wing is pretty unsanitary, but nonetheless, our next food item appears during one of Harry's many stays in the Hogwarts Hospital Wing:
"Hagrid sent him a bunch of earwiggy flowers that looked like yellow cabbages, and Ginny Weasley, blushing furiously, turned up with a get-well card she had made herself, which sang shrilly unless Harry kept it shut under his bowl of fruit" (Prisoner of Azkaban 183).
It is likely that the bowl on Harry's side table is filled with whole fruit. But below I have a list of the fruits that have appeared in every fruit salad to appear on my family's table for my entire life. Of course, you can substitute whatever you'd like when you prepare your own!
You Will Need:
1/2 watermelon, cubed
1 caneloupe, cubed
1 honeydew (or honey rock, depending on where you're from!), cubed
strawberries, hulled and quartered
raspberries (sometimes... but sometimes they can get squishy... so use your own judgement)
pineapple (unless you're like me and it makes you itchy!)
Mix everything together and enjoy! Yum!
